Loading A DataGridView (or DataRepeater) From A Text File As A Project Resource (not XML)?
Feb 15, 2012
So there's lots of examples of how to do this if your text file happens to be in XML format. However, my text file is not in XML format and as it contains over 172,000 rows I'm not that keen on adapting it (it's a dictionary)! The text file has been included in the project as a resource.
So far I've got a DataGridView (could use a DataRepeater if easier?), a BindingSource and a DataSet.
The DataSet has a DataTable already defined in the designer with one column.I've managed to load the text file into a String and then create a StringReader based on that String variable, however I cannot find anyway of loading those strings into the DataTable.
Dim listWords As String = My.Resources.WordList Dim strReader As New System.IO.StringReader(listWords)
'What now???There are some examples of using OleDb functionality but all assume you're loading from a text file residing somewhere in the filesystem, not a project resource.(I'm also assuming that on building the application the resources get embedded (somewhere) rather than being accessed from [AppDir]/Resources/[filename] ??)
I'm writing a VB.NET app where I want to load an internal text file from Resource. But the code shows Invalid URI: The Uri string is too long. The code is 'document.Load("C:UsersSouDocumentsVisual Studio 2010Projectsinfo.xml") document.Load(My.Resources.info) 'some processing job with XML node ... So, how to load the resource file ?
I made a text file (.txt) in my project by going to Add New Item and then Text File. I want to have my text file be loaded into the rich text box i have on my form but it doesn't work. It says it can find the file. This is my code:
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question. 2) How can I save data, Datagrid to Text file.
I found a code Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter Public Function ConnectCSV1(ByVal filetable As String) As DataSet Dim dataSet As New DataSet [Code] ..... I can load data with this code but I can't save.
My Text File must be like this: #IP 127.0.0.1 localhost
can anyone tell me if this option is available in VB.NET 05/08, I want to add Win32 resource file (.res) to project but i can't find any option to do that, and the option was in C#. This not a regular resource, it was created using native resources template. Below are the screenshots of Application tab in project property from C# and VB IDE. The option that im looking for is in red box on C# screenshot
How would I load a file in the WMP from the projects resources? formAudio.URL = My.Resources.formAudioWAV returns an error: Value of type 'System.IO.UnmanagedMemoryStream' cannot be converted to 'String'. It absolutley has to be AxWMP over My.Computer.Audio.Play.
Is it possible to have a datagridview on a datarepeater contol and, if so, heave the datagridview bound or filtered on two fields in the datarepeator, one of them an integer (an id) and one of them a date?
I've written the following sub to load a comma delimited file into my datagrid view but it's hanging up when it attempts to load the first two values into the cells of the datagridview. I think it's having trouble adding the cells to the datagrid. I have tried writting them directly using the .text of the specific row and cell but when I incremented to the next row it hung up because the row didn't exist (I think).
I generate my xml into "variable string str" by using "dataset.GetXml" and then I write the "xml which is contained in variable str" into "file.xml" by using sFile.WriteLine(str) while 'sFile' is a stream reader"My reason for using 'writeline' instead of 'dataset.WriteXml' because I need to encrypt the 'xml stored in 'str' before I store it into file.xml.I got everything fine for the encrypted result, and so does the decrypted result as well.Here's the decrypted result of my file.xml below (I have checked it the xml value which in str before encryption and which in decrypted file.xml. They are all match well)Here is my plain xml value before it got encrypted or decrypted which I stored it in variable str by using GetXml. I don't know for sure but my xml value doesn't contain declaration "<?xml version="1.0" encoding="utf-8" standalone="yes" ?>" like common xml used to have.All the xml file which I got from GetXml is just like below (No declaration like <?xml version="1.0" encoding="utf-8" bla ?>) Book 1 2010-09-22T14:43:00.0000000+07:00
And since I think it may not cause any problem then I keep coding and decrypt it which is going well and the decrypted result is perfectly same ofcourse.My problem is, when I try to make my xml value show in Data GridView by using the code below, and run the debug, it prompt an error said "could not find the file c:laFile.xml ".
ds = New DataSet path = System.IO.Path.GetFullPath(strFileToDecrypt) ds.ReadXml(path)
I am facing a "weird" problem with the DataGridView. In fact, I have a function, that loads each table of an xml file into a datagridview (27 tables all with same structure except one called Listes). In the datagridview I have a combobox column to select "type" (it's the 3rd Column, so it's index is 2 normally). The problem is that when I call the function loaddata for the first time, all work perfectly ! If I call it for a second time, to reload the data, I get an error of cast! I verified and it seems that first time I call the function the column that contains the combobox is column(2), but when I run it again automatically the indexes of the columns are changing and am getting the error, because the column that contains the combobox is becoming column (3) and that explains the cast error because the column'(2) is not anymore the combobox so the cast will fail ! What I can't understand is why it's reordering that way my columns automatically ?
Here is the code: vb.net Sub LoadData(Path As String ) Dim oData As DataSet oData = New DataSet oData.ReadXml(Path) Dim i As Integer Dim MaGrille As DataGridView [Code] .....
So i created resource file New --> new file --> Native Resource Template Then added icons with custom id, like "x", "u_100", .. so i understand, what the files (in my case icons) is.. And i saved as 32-bit resource file (*.res) So i have a question, how can i use these files inside of resource file in my apps? i know how to add icons in to my app.. Me.Icon = New Icon(C:/icon.ico)
I'm trying to write an application that requires information to be saved once the application has been exited. In order to do this I have been experimenting with storing the data in text files. More specifically I've been looking into adding text files as application resources. I am using VB Express 2008 and added the text file resource through the application tab>>Resources>>Add Resource>>Add new text file. I am able to use my.resources.TextFile1 to read the text file but I am unable to write anything to it. I have tried using my.resources.TextFile1.replace and .insert but neither of those are working out. I was thinking there is maybe a read only setting somewhere, but I have not been able to find any information on this issue.
I cannot seem to get my image resources to load into PictureBox1.I can see all the images I added as resources in the solution explorer.They are a series of PNG files with names associated with countries.I am at the beginning stages of randomly changing the image that is displayed in PictureBox1, but I cannot even get the first image to load.Here is my code so far. When I click on Button2 I can see that my array returns a random country, but no image loads.I even tried typing in several of the countries names as well as the country name followed by png (e.g. chine.png) and again no image loads.
Public Class Form1 Dim randomObject As New Random() Dim Flags() As String = {"australia", "brazil", "china", "italy", "russia", "south africa", "spain"}[code]......
I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
Is there any way to have a datagridview on a datarepeater with more than 1 row showing?
I have a datagridview on a datarepeater control. The datarepeater and the datagridview are joined on a common field in 1-to-many fashion. The form is designed so that there are 2 rows of the datarepeater visible at any one time. The datagridview is populated in the datarepeater's drawitem event The problem is that it behaves as if there is only one datagridview total rather than one datagridview per row. The drawitem event executes when you scroll to a row. Because 2 rows of the datarepeater are visible, the fill code is executed twice when the form is opened. But the second fill overrides the first one. So you've got this form with 2 different rows but the data in both datagridviews is the same but is right only for the bottom one.
Is there any way to correct this? If I made only 1 row visible, that would eliminate the wrong data. But I want to be able to show more that 1 row at a time.
i have been hunting the web for a solution or example to my problem which is loading and xml file into DataGridView with combobox for the cells and then loading the comboxes with data that the user can choose from to change the cell value to and output an updated xml file. Below is my code with the column creation commented out for now, with this code the 7 columns are added with comboboxes to the datagrid but when I read in the xml file its adds the data to another 7 columns on the end and not into the columns I have created first.
Im having problems with one section. I have imported 4 text files that have lists of computers in them, and i want to read the computer names into an array so i can use them from there. I have the attribute in them set as embedded Resource as well. So if anyone could check this code and see what is wrong or right, and how i can read the file into the array that is established that would be awesome.... Ill be researching this non stop untill i figure it out, but thought someone on here might have an idea

I am trying to read a text file into a text box, and show the progress bar loading. Sometimes if the text file is big, i don't know when it will finish reading it. This is basically the code i use to read a text file, but i don't know how to show the progress bar.
how to access the text file that I added to the project as a resource file. I want a list of words to be part of the .exe file, not contained in a separate .txt file on the hard drive.What do I need to change?
vbcode Dim reader1 As New System.IO.StreamReader("c:1.txt") For i As Integer = 0 To 25 BlanksOne(i) = reader1.ReadLine() Next i
I would like to know how to write to a text file that is added to resources and then have it show the contents in a text box.But I would like to have it on a timer so every second it will refresh as I am trying to make an instant chat program.Also I would like to note that I want it to delete everything after all the users have closed the program. Is there any way to make it so the text file is empty when there is no body using the program any more?

I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click If File.Exists("Login Config.txt") Then Dim ioFile As New StreamReader("Login Config.txt") Dim ioLine As String ' Going to hold one line at a time
I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file
i am using vb.net 08. I have a php file loading into a text box. and then i have an external text file. the text file looks like this:"text 1= text 2 text 3 = text 4 etc"I need the program to search for terms inside the text box that are on the right side of the equal sign and replace it with the one on the left
I picked the idea to make a little agenda for my own use and my plan was to edit a txt file using the RichTextBox. I want to use a DateTimePicker too, so that I can load a specific text file for the date chosen so that I can edit it. Does anyone have an idea how I can use the DateTimePicker to create and load certain txt files related to the same date?
I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@ :/ Regular text files load fine. Here is the CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*") CommonDialog1Open.ShowDialog() rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName)) I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.
